15. PMC CONTROL FUNCTION
1203
The PMC can directly control any given axis, independently of the CNC.
In other words, moving the tool along axes that are not controlled by the
CNC is possible by entering commands, such as those specifying moving
distance and feedrate, from the PMC. This enables the control of turrets,
pallets, index tables and other peripheral devices using any given axes of
the CNC.
Whether the CNC or PMC controls an axis is determined by the input
signal provided for that particular axis.
The PMC can directly control the following operations:
(1) Rapid traverse with moving distance specified
(2) Cutting feed -- feed per minute, with moving distance specified
(3) Cutting feed -- feed per revolution, with moving distance specified
(4) Skip -- feed per minute, with moving distance specified
(5) Dwell
(6) Continuous feed
(7) Reference position return
(8) 1st reference position return
(9) 2nd reference position return
(10) 3rd reference position return
(11) 4th reference position return
(12) External pulse synchronization -- Main spindle
(13) External pulse synchronization -- first manual handle
(14) External pulse synchronization -- second manual handle
(15) External pulse synchronization -- third manual handle (for M series
only)
(16) Feedrate control
(17) Auxiliary function, Miscellaneous function 2, Miscellaneous
function 3
(18) Selection of the machine coordinate system
(19) Torque control
The PMC is provided with four paths to control these operations using
input and output signals.
By issuing commands through these four paths, the PMC can
simultaneously control multiple axes separately. Use parameter No. 8010
to determine which path controls which axis. Commands may be issued
through one path to two or more axes, thus allowing the PMC to control
multiple axes using one path.
